Kodi fakitale ya chubu chotenthetsera uvuni chamagetsi imakuuzani kuti ufa woyera womwe uli mu chubu chotenthetsera ndi chiyani?

Ogwiritsa ntchito ambiri sadziwa mtundu wa ufa womwe uli mu chubu chotenthetsera uvuni, ndipo mosadziwa tidzaganiza kuti mankhwala ophera tizilombo ndi oopsa, ndipo tidzada nkhawa ngati ndi owopsa kwa thupi la munthu.

1. Kodi ufa woyera womwe uli mu chubu chotenthetsera uvuni ndi chiyani?

Ufa woyera mu chotenthetsera cha uvuni ndi ufa wa MgO, womwe uli ndi mphamvu zabwino kwambiri zoyendetsera kutentha komanso zotetezera kutentha.

2. Kodi ufa woyera umagwira ntchito yotani mu chubu chotenthetsera uvuni?

(1) Imagwira ntchito yoteteza kutentha ndi kuyendetsa kutentha, ndipo waya wotenthetsera wamagetsi ndi thupi lotenthetsera komanso thupi la munthu, ndipo ufa wa magnesium oxide umateteza kuti usakhudze chipolopolo chachitsulo kuti utsimikizire kuti pamwamba pa chubucho palibe chaji;

(2) Tetezani waya wotenthetsera wamagetsi ku mphamvu zakunja;

(3) Sizipanga mayankho a mankhwala pogwiritsa ntchito mawaya otenthetsera amagetsi ndi zipolopolo zachitsulo, zimatha kupirira kusintha kwa kutentha, ndipo sizimaphulika machubu chifukwa cha kusintha kwadzidzidzi kwa kutentha;

(4) Kukana kutentha kwambiri, pafupi ndi kuchuluka kwa waya wotenthetsera, zomwe zimapangitsa kuti waya wotenthetsera usasunthike pokonza chubu chotenthetsera.

3. Kodi ufa woyera womwe uli mu chubu chotenthetsera uvuni ndi woopsa?

(1) Ufa wa MgO womwe uli mu chubu chotenthetsera uvuni si woopsa, ndi wopanda fungo, wopanda kukoma, wopanda poizoni, womwe ndi ufa woyera wosapanga mawonekedwe, womwe ndi wa zinthu zoteteza chilengedwe;

(2) Magnesium carbonate, magnesium oxide powder ndi talc powder ndi mafuta ofunikira omwe amagwiritsidwa ntchito kwambiri kwa othamanga ndipo savulaza thupi la munthu;

(3) Ngakhale atamezedwa mwangozi, kupatulapo ziwengo za munthu payekha, magnesium oxide imalowa m'mimba ndikuchitapo kanthu ndi hydrochloric acid kukhala magnesium chloride, yomwe imapezeka m'madzi a m'nyanja. MgO ingagwiritsidwe ntchito ngati mankhwala oletsa asidi, otsegula m'mimba, oletsa asidi m'mimba, komanso oletsa asidi m'mimba.

Ngati mukufuna kugwiritsa ntchito chubu chathu chotenthetsera uvuni, mutha kulumikizana nafe mwachindunji!
